Description

Vernonia arkansana, also known as Arkansas ironweed and great ironweed, is a species of perennial plant found in south-central United States. The flowers bloom from August to September and are pink-purple coloured.

Arkansas ironweed is pollinated by various insects such as bees, butterflies, and skippers. Bees like Melissodes vernoniae are frequent visitors to Vernonia plants in general. Various caterpillars of moths also enjoy the feeding. It also attracts hummingbirds.

Type: Hardy perennial

Hardiness zones: 3-8

Height: 4-6 feet (1.2-1.8 m) high, and 3-4 feet (0.91–1.22 m) wide

Note: Ornamental use only. These seeds and/or plants are poisonous.

Seeds per pack: 10

Germination: Start these seeds right away for best germination rates. These seeds require a period of cold. Sow the seeds just under the surface of a sterile seed-start mix. Leave them at room temperature for 2 weeks. They will not grow yet. Then cover them with plastic and place in a fridge for 5-6 weeks. Be sure they stay moist. After the cold stratification period they are then brought back to room temperature for them to germinate. If possible, the best location for sowing in March, April and May, is in cold frame or a cold greenhouse where they will receive the cold period and fluctuating temperatures naturally.
